According to the site Computerworld, scientists from Stanford University are able to develop a version of the lithium-ion battery, protected from overheating. The researchers used a polyethylene film coated nickel particles, which, in turn, suffered a conductive layer graphene. Under normal operating conditions, the particles come into contact, but as the film is heated and expanded contact between them disappear. After cooling down, it will be able to earn back.
Scientists note that the temperature threshold can be adjusted by controlling the density of nickel particles and the type of polymer film. Now break occurs at a temperature of about 70 degrees Celsius. Related Products :
